i To all whom it may concern Be it known that I, BENJAMIN L.. Con- Nnmus, a citizen of the United. States, residing at Hutchinson, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Oil-Burners; and I do declare the following to be a full, clear, and cxactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,

which form a part of this specification.

My invention relates to oil burners, and more particularly to a burner adaptedfor use in heating stoves or hot air furnaces, the principal object of the invention being to provide a device wherein oil may be vaporized and mixed with air to secure proper combustion. r y

In accomplishing this object I haveprovided the improved details of structure hereinafter described and illustratedin the accompanying drawings, wherein Figure I is a perspective view of an oil burner constructed according to my invention, showing its combination; with the fire bowl of a stoveor furnace, the latter being in section, for better illustration. Fig. II is a central, vertical section of the parts shown in Fig. I. Referring more in detailto the parts; 1 designates the fire bowl of a stove or furnace and 2 the grate, which may be of the usual construction. Supported on the grate 2 is a pan 3,

preferably of cast metal, and having a central aperture 4 through which the nipple 5 of an oil supply pipe 6 is projected.

Seated in the pan 3 is a burner body 7,

i which is also preferably of cast metal, of

cylindrical shape and provided with an inturned flange 8 by which it is secured to the pan by screws 9, or the like, the body 7 being set in from thesides of the pan 3 to provide an annular space 10, for a purpose presently set forth. I

On top of, and preferablyintegral with,

the body 7 is a dome 11 which covers the topof the burner body and depends at the sides thereof to form an annular, upwardly opening channel 12 for receiving oil from the feed conduit 13 which connects with the supply nipple 5 and has a laterally turned upper end adapted for droppingioil into the annular-channeh t t Opening through the body of the burner immediately below the channel v12, and

above thetop of the pan areapertures 15 through which oil delivered into the in' terior of. the burner by-J overfloy from the channel maypass to flow down the outer surface of the burner-body; vinto the annular space between the-burner body and the sides of the-pan; a

Also seated on the grate 2 is an annular hood 16 forming an air chamberl? around the pan 3 and above; the grate, the upper portioniof said hood being substantially level with but spaced from the top] ofthe pan 3 to form an annularqport 18 through which air passing upwardly through the grate of the fire bowl and throughthe chamber 1,7 may pass to mix with the oil vapor and thereby provide a combustible fuel mix- A In order to seal the burnerqhoodand thereby prevent air from entering :thefire bowl except through the'annularport 18 I fill the lower portion of the fire bowl, around the hood, with akpacking of asbestoscement 19. v

Inusingithedevice, presuming theparts tobe assembled as described, oil'is allowed to. flowv through the; conduit 13;" and drop into the dome channellQ, overflowing the inner edge of the channel and filling the interior of the burner body until it reaches the level ofthe apertures 15, through which it passes to fiow down the outer surface of the burner body into the pan 3. The oil is then ignited in the pan and while burning heats the burner body and dome so that oil in the dome channel and interior. of the burner body is vaporized and, by expansion,-

is forced out through the apertures 15 to the outside of the burner. The vapor upon leaving the burner body mixes with air rising through the annular; port 18 to form the combustible mixture which is burned within the furnace.

It is apparent that the burning oil con- I tinues to heat the dome and the upper portion of the burner body so that vaporization of the oil continues as long as the feed is maintained and the vapor burned.

Having. thus described my invention, what I claim as new therein and desireto secure by Letters-Patent, is:

Claims:

1. An oil burner comprising a body member, an imperforate dome cooperating there with to form an annular oil reservoir, a conduit extending through the body member and having a laterally turned upper end adapted for delivering oil into the reservoir, the body member of the burner having transverse apertures located below the reservoir, and a cup surrounding the lower end of said body member for the purpose set forth.

2. An oil burner comprising a body member, an imperforate dome integral therewith and depending over the upper edge thereof to form a reservoir, and a supply conduit extending through the body member and having a laterally turned end adapted for delivering into the reservoir, said body member being provided with transverse apertures below the reservoir, forming ports for the escape of vapor generated within the reservoir for the purpose set forth.

3. In an oil burner, the combination with a fire bowl, of a pan seated in the fire bowl, and set in from the sides thereof, a body member having outlet ports above the pan, and having an integral dome thereon extending downwardly at the sides of the body and forming an annular reservoir, a conduit leading through the body member, and adapted for delivering into said reservoir, and a hood member seated in the fire bowl about thepan, and having, a port adjacent the pan adapted for delivering air into proxifmity to said outlet ports, for the purpose set orth.

4. In an oil burner, the combination with Gopiel'of this patent may be obtained for five cents each, by addressing the a fire bowl, of a pan seated in the fire bowl,

and set in from the sides thereof, a body member seated in the pan and set in from the sides thereof to form an annular channel, and having outlet ports above the upper edge of the pan, an imperforate dome in tegral with said body member and extending downwardly at the sides of the body to form an annular reservoir, a conduit leading through the body for delivery into said reservoir, and a hood member seated in the fire bowl and spaced from the pan to form a port for delivering air into proximity to said outlet ports, for the purpose set forth.

5. In an oil burner, the combination with a fire bowl, of a pan seated in the fire bowl and set in from the sides thereof, a hollow body member secured to the base of said pan and set in from the sides thereof, and having outlet ports above the base of said body member and above the upper edge of said pan, an imperforate dome integral with and forming a closed chamber within said hollow body member, and extending downwardly at the'sides thereof to form an annular reservoir, a. conduit leading through said body and'closed chamber for delivering into said reservoir, and a hood member seated in the fire bowl and spaced from the pan to form a port for delivering air into proximity to said outlet ports, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
